- THE WEEK, Page 23HEALTH & SCIENCEAnd Now, Robodoc!
-
-
- In a medical first, a robot in California performs invasive
- surgery
-
-
- Medical robots have been used to locate hard-to-find tumors and
- guide a surgeon's scalpel but have never actually performed
- surgery on people -- at least not in the U.S. Now that line has
- been crossed. At Sacramento's Sutter General Hospital, a 90-kg
- (200 lbs.) machine called Robodoc has operated on its first
- human patient: a 64-year-old man with a bad hip.
-
- The robot played a key role in a total-hip replacement,
- one of 500,000 such operations performed each year. The trick
- in these procedures is to cut a snug hole into which the
- artificial hip snaps. The standard method is to jam a tool into
- the thighbone with a hand-held mallet. Robodoc, using the
- high-speed drill at the end of its mechanical arm, can ream a
- cavity that is 20 times as precise.
-
- Robosurgery doesn't have to stop at the hip. In Europe,
- where officials are less squeamish about such things, robots
- have assisted in operations on the brain, the prostate and the
- inner ear.
